Abstract
|
|
|
|
Shoot parts of a monocarpic and short day plant Orostachys japonicus have been used as a herbal medicine. The study was carried out to examine the effect of transplanting time (May 30, June 30, July 30) of its seedlings on its growth, morphological characters, and flowering. Two hours night-break treatment at midnight was done since Aug. 25 when samples were taken afterward every 4 weeks. Growth, morphological and flowering related characters were measured from each sample. Plant height and inflorescence length became longer with delayed transplanting time. Number of leaves including bracts and stem diameter were more and thicker when transplanted on June 30 than two other treatments. Leaves and bracts, stem, root, shoot and total dry weights showed nearly the same result to the number of leaves although floret dry weight were increased as transplanting time was delayed. Although florets were most formed when transplanted on June 30, they were not flowered because of the night-break treatment, meaning that the transplanting time had little effect on its growth and anthesis of the florets.
